To all whom imag/1f concern:

`Be it known that I ELIAS B. DE LAM-Arm, a citizen of the United'States,` -cresiding .at

`LosAngeles,in the county-.bf Los Angeles so as to be more convenientfor use of a traveler who may desire to apply the fastener temporarilyto the window o a room which he transitorily occupies.

Objects of this invention are simplification and reduced cost.

The invention may be embodied in lnumerous forms, and I do not limit thesame to specific contrivances.

The accompanying drawings illustrate the invention.

Figure 1 is a view of the invention in one of its forms as ap lied readyfor use. Fig. 2 is a view of anot er embodiment of the invention. Figs.3, 4. and 5 show other embodiments of the invention omitting the guard.Fig. 6 is a cross-sectional view of an line :rm-:107, of either Fig. 1or 2.

embodiment of the invention. This view may be regarded as practically asection on Fig. 7 is a cross-sectional view which may be regarded astaken on line indicated by :r6-x7, of Figs. 1 and 2. The variations inform shown in Figs. 6 and 7 are applicable to the device as illustratedin Figs. 1 and 2. Fig. 8 is a plan of a keeper detached.

1 designates a keeper intermediately bent as at2 and perforatedvertically as at 3, the bend 2 being adapted to fulcrum on the top ofthe lower sash 4 to which the keeper is to be pivoted by a screw 5 whichmay be of any desirable formeither rovided with a screweye 6 or with aslotted) head 7.

'8 is a loop which engages the to of the lower sash 4, and which isperforated as at 9 to receive the screw 5. It may have a perforated foot10 through which a fastener as screw 11 may be inserted to secure theloo to the window-sash independently of the fulcrum-screw 5.

By perforating the plate verticall as at 3,

that is to say, atI approximately rig t angles to a straight`linedrawnfrom endto endrof the -two .limbs 4of .the ,bent plate, the.plate may .-be fastened bythe l very simple device yishownpso as toeffect the locking of theisash and yetf-be free :to yieldto thepressure-.cof a thumb-or` ngerion the free end of` the-plate. i Bymsing`the screw-eye. in combination k.with such `:vertically i perforatedpl-ate, :perfect freedom for a tilting movementnof the `plate -forlocking .l and unlocking the. sash is secured, together with perfectsecurity against any sliding of the bent plate on to of the sash.

12 is a uard plate whic may have a roughened ace 13, and may be fastenedto the upper sash 14 by screws 15; said plate being seated in said uppersash 14. The

sash-engaging portion 16 of the keeper 1 may terminate in a bent portionwhich maybe variously formed, different forms of the same being shown at17, 18, 19. In Fig. 2 the sash-engaging portion 16 is shown as an unbentend of the keeper 1. In the several views the different forms of keepersare indicated by the character 1, different forms being designated bythe addition of an eX- ponent.

The purpose of the loop Sis to form a positive support for the head ofthe screw 5 in order that the screw may be tightly screwed Vdown intothe Window-sash Without tightly engaging the keeper. It isnecessary'that the keeper be free to respond to gravity, and thesash-engaging limb of the same having the ortion 16 is of greater Weightthan the free llimb 20, so that gravity normally holds the sash-engaginglimb in engagement with the sash, so that as the lower sash lowers orthe upper sash rises the limb will rest against said sash but will notimpede the movement thereof; but on the reverse movement of either sashwhich would tend to open the window the friction ,of the sash on the endof the keeper causes the keeper to wedge tightly against thesash, thusto lock the window against further movement.

The guard plate 12 may be roughened where desired, the purpose of saidguardplate being to protect the upper sash from defacement'by theengagement of the keeper. The character of such roughening isimmaterial, all that is necessary being that the friction between theplate and the keeper shall be sufficient to prevent the slipping of theone past the other when the tendency of the Window is to open.

By this invention in its simplest form, the

traveler is supplied with a fastener consisting of two extremely simpleparts which can be most expeditiously applied to and taken filorlp thewindow with but slight exercise of s i It is'not necessary to thelocking action that the plate be employed, and said plate has beenomitted from some of the views. In the simplest form of this inventionthe head of the screw may be in the form of an eye as shown at 6, thusenabling the fastener to be applied to a window without the use oftools. This simple form adapts the device especially for the use oftravelers who may desire to protect themselves against burglars bytemporarily applying fasteners to the windows of their temporaryapartments.

What I claim is:

1. A window sash fastener comprising a plate bent intermediately andperforated vertically substantially as set forth at the bend, and ascrew extending through the perforation to detachably fasten the plateto the window-sash.

2. A window sash fastener comprising a keeper bent intermediately andperforated vertically at the bend, a perforated loop over the bend,means to fasten the loop tothe top of the lower sash, and a screwextending through the perforations of the loop and keeper to seat in thetop of the lower sash.

In testimony whereof, I have hereunto set my hand at Los AngelesCalifornia this 28th day of January 1907,

ELIAS B. DE LA MATYR.
